摘要： PURPOSE: To improve safety of a vehicle and to reduce wear of a brake lining by applying stable auxiliary brake without increasing the burden of the electric equipment system and the cooling system of a vehicle. CONSTITUTION: The power of a semitrailer vehicle 1 is transmitted from an engine 5 to the rear wheels 11 of a tractor 2 through a clutch 7, a transmission 8, a propeller shaft 9, and a rear axle 10. A retarder 4 with an exciter is arranged at a trailer 3 separately from a service brake device and worked on a rear shaft 15 separately from the service brake device. Through the working of the exciter, the power consumption of the exciting coil of the retarder 4 is compensated and a harness 6 is thinned.

摘要： PURPOSE:To obtain a retarder in which the direction of an output shaft is shortened, which is lightweight and which can be miniaturized by a method wherein a plurality of permanent magnets are fixed and bonded to the outer circumferential face of a brake drum so as to face an exciter coil and a power-generation coil. CONSTITUTION:An eddy-current cylinder 7 is arranged and installed at the outside of a brake drum(BD) 1 in such a way that its axial center is identical to that of the BD 1. A cylindrical support member 8 which is composed of a magnetic material is arranged in a space which is formed by the outside of the BD 1 and by the eddy- current cylinder 7. A pole core(PC) 11 which is composed of a magnetic material is attached to the outer circumferential face of the support member 8, and an air gap(AG) is formed between the PC 11 and the eddy-current cylinder 7. An exciting coil 13 is wound on the PC 11. An exciter core 14 is fixed and bonded to the inner circumferential face of the support member 8, and a power-generation coil 15 is wound. Permanent magnets 16 are arranged at equal intervals on the outer circumferential face of the BD 1 in the order in which their poles are alternately different. The magnetic flux of an exciter flows through a magnetic circuit which is formed of the permanent magnet 16, the AG, the exciter core 14, the AG, the adjacent permanent magnet 16 and the cylindrical part of the BD 1.

摘要： PURPOSE:To generate brake torque stably through relative rotation of a field core and a eddy current cylinder by disposing a discharge fan in a gap at the end face part of a eddy current plate of the eddy current cylinder and making a ventilation window through the eddy current cylinder thereby suppressing temperature rise of the field coil and the eddy current plate. CONSTITUTION:When a field current flows through a field coil 4, pole 3 of a field core 2 is magnetized to generate eddy current in an eddy current plate 5 rotating while opposing thereto thus producing brake torque. Consequently, eddy current loss is produced in the eddy current plate 5 which is thereby heated while Joule's heat is generated in the field coil 4 which is thereby heated and the temperature of the pole 3 also rises. A fan 9 is disposed on the eddy current plate side in an air gap formed between the eddy current plate 5 and a fixed object 1. Upon rotation of the cylinder 6, air is ventilated through the window 10 and heated air in the eddy current cylinder 6 is discharged through the gap between the end face part of the eddy current plate 5 and the fixed object 1 to the outside thus restraining temperature rise of the eddy current plate 5, the field coil 4, and the like.

摘要： PURPOSE: To provide optimum braking force in accordance with a load weight, regardless of the loaded or unloaded state, by detecting the load weight from deflection of a suspension, and controlling breaking torque of a retarder. CONSTITUTION: When a suspension position signal from a suspension position sensor 22 is entered in a control circuit 43 of a retarder 20, the magnitude of position signal, namely the magnitude of field current carried in a field coil 34 is controlled by a linear amplifier 43 in the retarder 20 in accordance with the carrying load weight. Then, larger braking force is set in the retarder 20 when the inertia force of a vehicle is large, while small braking force is set in the retarder when the inertia force is small. In this way, the braking force can be set in accordance with the deflection of the suspension 21.

摘要： PROBLEM TO BE SOLVED: To attain waterproofness by a method wherein both lead wires are floated partly from the outer face of a first flange part between both edge parts of coils, soldering parts of both lead wires and both grommets and support protrusion parts which support a covering part so as to be brought into close contact on the whole circumference of the lead wires are installed so as to protrude on the outer face of the first flange part. SOLUTION: Both lead wires 45 are supported partly by support protrusion parts 48 which are formed so as to protrude to the outer face of a first flange part 39b between both end parts 16a, 16b of exciting coils, soldering parts 47 of both lead wires 45 and both grommets 46, and both lead wires 45 are floated from the outer face of the first flange part 39b. As a result, a molten resin creeps easily into parts between the first flange part 39b at a bobbin 30 and the lead wires 45 in places in which the support protrusion parts 48 are arranged and installed, and the molten resin, i.e., a covering part 40, is brought into close contact over the whole circumference of the lead wires 45. Consequently, it is possible to surely prevent water from creeping up to the soldering parts 47, and it is possible to obtain an excellent waterproofness.
