Embodiment Construction

[0031] The patent of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The technical personnel of the present application have found through research that in the existing brake drag measuring device, the connection mechanism between the wheel and the test equipment is provided with a connection transition device such as a flange. As shown in the figure, the vehicle wheel drag torque measuring device in the prior art is connected to the wheel through a flange, and the flange shaft 2-3 is connected to the center of the flange through bolts, and the flange is away from the flange shaft. The other side is provided with a sleeve 2-2, and the sleeve 2-2 is threadedly connected to the flange, and is sleeved on the bolt head of the wheel locking bolt. However, there is a fit gap between the connecting transition devices such as flanges and the unit bolts of the wheel hub, which makes it impo...

Abstract

The invention discloses a wheel center self-adaptive positioning structure and equipment for brake retarding torque test. The structure includes a flange plate, the flange plate is provided with a first penetrating hole used for being connected with an equipment coupler, the flange plate is further provided with a plurality of second penetrating holes, the second penetrating holes extend in the radial direction of the flange plate, and a flange plate positioning pin used for being connected with a hub unit bolt is arranged in each second penetrating hole in a sliding mode. The second penetrating hole is provided with first wedge-shaped faces symmetrically arranged in the extending direction of the second penetrating hole, and the flange plate positioning pin is provided with second wedge-shaped faces matched with the first wedge-shaped faces. Center self-adaptive positioning between the wheel and the test equipment is realized, and the wheel center self-adaptive positioning structure has the technical characteristics of simple structure, convenient use and maintenance and the like.

Description

technical field [0001] The patent of the present invention relates to the field of automobile braking, a part of the data automobile braking system test equipment, which is suitable for various types of vehicles such as energy-transfer passenger vehicles, new energy passenger vehicles, and military off-road vehicles. Wheel center adaptive positioning structure for blocking torque test. [0002] technical background [0003] With the continuous progress of society, the country's energy-saving and environmental protection requirements for automobiles and people's economic requirements for automobiles are also gradually increasing, and enterprises are facing increasing pressure on the economical development of automobiles. Driving resistance is an important factor affecting the economy of the vehicle, and the braking retardation torque generated by the friction torque between the brake caliper and the brake disc is an important part of the sliding resistance. Its size has a cer...
