Embodiment Construction

[0029] The specific implementation of the device will be further described below in conjunction with the figures.

[0030] like figure 1 As shown, it is a schematic diagram of the overall structure of the device (in order to show the internal structure of the device, the support arm 7 is cut along the plane of symmetry). The whole device is completely symmetrical, so only the name of one side of the device is marked in the figure. The basic components of the device include an angle capture part 14, a bracket arm 9, a hydraulic distribution part 10 and a sliding rheostat part 11, wherein the angle capture part 14 is composed of a ball stud 1, a slider 2, a lower gland 3, an interlayer 4, and a fixing screw 5, upper gland 6, ball head 7 and groove 8 are formed. The ball stud 1 and the ball stud 7 are processed into one body, the ball stud 7 and the supporting arm 9 are fitted together, the ball stud 1 is fixed on the main vehicle through the thread at the lower end, and the sup...

Abstract

The invention discloses a differential distribution device of travel trailer braking force. The differential distribution device of the travel trailer braking force can be divided into four parts, that is, an angle capturing part, a supporting arm, a slide rheostat part and a hydraulic distribution part. The angle capturing part can capture the horizontal rotation angle of a ball head and convertthe rotation angle into the movement of slide rheostat sliding sheets. The device is provided with two slide rheostats. The change of a resistance value of the rheostats directly causes the change ofthe stroke of a push-pull electromagnet in the hydraulic distribution part, so that the change of the position of a piston in a hydraulic cavity is caused. The hydraulic cavity communicates with brakes of a left wheel and a right wheel of the trailer. The movement of the piston changes the braking force generated by the brakes, and the braking force applied to the left wheel and the right wheel isdifferent, so that the differential distribution of the braking force of the trailer is achieved. Mechanical transmission and hydraulic braking methods are adopted, and the differential distributiondevice of the travel trailer braking force has stable work and high reliability and is convenient to install, disassemble and maintain.

Description

technical field [0001] The invention relates to the technical field of brakes for a trailer type caravan, in particular to a braking force differential distribution device for a trailer type caravan. Background technique [0002] When studying the movement of a towed caravan, the towed vehicle is generally called the main car, and the towed caravan is called the trailer. When the towed caravan is turning, a corner will be formed at the connection between the main car and the trailer. This corner has a great influence on the stability of the RV movement. In order to ensure the smooth turning of the caravan, different braking forces need to be applied to the left and right wheels of the caravan, and as the corner changes, the applied braking force should also change accordingly. In the existing scheme for realizing the differential braking of trailer-type RV, such as the patent application number 201810128501.6, the detection mechanism, the electronic control unit ECU and th...
