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 that, in the existing brake drag force measurement 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 measurement device in the prior art is connected to the wheel through a flange, and the flange shafts 2-3 are 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, the sleeve 2-2 is threadedly connected to the flange and sleeved on the bolt head of the wheel locking bolt. However, there is a gap between the connecting transition devices such as flanges and the bolts of the hub, which makes it impossible to achieve stable ce...

Abstract

The invention discloses a wheel center self-adaptive positioning structure and equipment for braking retarding torque testing, which includes a flange plate, and the flange plate is provided with a first through hole for connecting a coupling of the equipment, The flange is also provided with a plurality of second through holes, the second through holes are arranged along the radial extension of the flange, and each second through hole is slidably provided with bolts for connecting the hub unit The flange plate positioning pin; the second through hole has a first wedge-shaped surface arranged symmetrically along its extending direction, and the flange plate positioning pin has a second wedge-shaped surface matched with the first wedge-shaped surface. The invention realizes the center self-adaptive positioning between the wheel and the test equipment, and has the technical characteristics of simple structure, convenient use, convenient maintenance and the like.

Description

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