Description

Technical Field

[0001] The utility model relates to the field of automobile parts, and more specifically to an electromagnetic brake of a driving wheel of a trailer caravan. Background Art

[0002] The principle of electromagnetic brake is that when the excitation coil is energized, a magnetic field is formed to generate suction, and the electromagnet will be attracted to the brake drum. The rotation of the brake drum drives the shoe to open, and the friction between the shoe and the brake drum forms a braking torque to achieve the braking effect. It is sturdy and durable, easy to maintain, and has a large speed regulation range; but the efficiency is low and the temperature rises at low speeds, so heat dissipation measures must be taken. This type of brake is often used in machinery with vertical loads. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide an electromagnetic brake for the driving wheel of a trailer caravan, which can solve the problem that the axle brakes of the current mainstream caravans are mainly passive brakes and the structure cannot be assembled on a driven vehicle model.

[0004] To solve the above technical problems, according to one aspect of the utility model, more specifically, a driving wheel electromagnetic brake of a trailer caravan comprises a wheel hub shaft, a plug interface is opened on the left side of the wheel hub shaft, a clamping column is fixedly connected to the right side of the wheel hub shaft, and a brake drum is fixedly connected to the right side of the wheel hub shaft through the clamping column, the wheel hub shaft and the brake drum are fixedly connected by tire bolts, a bearing ring is fixedly connected to the outer wall of the clamping column, a bearing seat is clamped and connected to the left side of the bearing ring, a retaining spring is fixedly connected to the left side of the bearing seat, and a brake chassis is fixedly connected to the left side of the bearing seat.

[0005] Furthermore, the bearing seat and the brake base plate are fixed to the suspension connecting flange by bolts.

[0006] The beneficial effects of the electromagnetic brake of the driving wheel of a trailer caravan of the utility model are:

[0007] The motor-driven drive and brake of the torsion beam axle and independent suspension of the trailer house are effectively connected and realized, which effectively solves the problem of effective connection and coordination between the drive wheel and the transmission shaft, and the connection problem between the drive shaft and mechanism and the brake due to wheel bouncing, improves transmission efficiency, improves driving comfort, and adopts compact electromagnetic brakes to meet the towing function of the trailer caravan and the expanded function of the synchronizer brake of the trailer caravan. It has a convenient structure, occupies little space, has low energy consumption, and has a low unit cost. BRIEF DESCRIPTION OF THE DRAWINGS
