Problems solved by technology

But for the electromagnetic retarder, it is necessary to supply power to the excitation coil of the retarder, and the power consumption is large
Installed on the trailer, the power supply needs to be drawn from the tractor, which increases the cable cost and safety of the vehicle, and affects the stability of power consumption of other electric equipment of the vehicle

Abstract

The invention discloses a self-excitation type retarded braking axle, which belongs to the technical field of automobile auxiliary braking, and comprises a retarded braking mechanism, a reversible motor mechanism, a half-axle mechanism and a control mechanism, the self-excitation type retarded braking axle is mainly applied to braking of a trailer, directly replaces an existing supporting axle of the trailer, and performs retarded braking on the trailer. Energy is recycled through the integrated generator, electric energy is provided for the retarding brake mechanism during working, and the reliability of the integrated axle and the stability of a vehicle power system are protected; the stored electric energy can be supplied to a motor winding, and performs boosting in starting for providing a driving force to the vehicle. According to the self-excitation type retarding brake axle, the retarder and the motor are integrally designed in the middle of the axle, and the half axle is detachable; the retarder is designed to be of a differential structure, and the original differential function of the axle is guaranteed; according to the self-excitation type retarding braking axle, the current of the magnet exciting coil of the retarding braking part is controlled, so that the braking torque is controlled in a gear and step-by-step mode.

Description

technical field [0001] The invention belongs to the technical field of automobile auxiliary braking, in particular to a self-excited retarding brake axle. Background technique [0002] At present, the number of heavy-duty cargo transport vehicles in my country is huge, among which trailers account for about half of the heavy-duty cargo transport vehicles. In order to ensure the safe driving of vehicles, it has become an inevitable trend to install retarders. However, the installation position of the retarder on the trailer is limited to a certain extent. There is no power in the trailer, the wheel speed is low, and the retarder's work is limited. The current best method is to integrate the retarder with the axle, so that the braking force of the retarder can directly act on the trailer with a larger load and inertia, so as to maintain the stability and safety of the vehicle during braking. [0003] The electromagnetic retarder is a non-contact braking safety auxiliary brak...
