Embodiment

[0008] Embodiment: scrape off the top 5mm thread of the axle sleeve pipe top 5mm of the Dafa brand small passenger car produced in Tianjin, and car out an annular groove with a width of 2mm and a depth of 2mm at the back 2mm; The interval is 120°safety pin groove, and its size is 3×3×5mm. There are 3 safety pin slots of the same size correspondingly on the outer nut of the fixed wheel hub; insert 3 safety pins with a size of 10×3×3mm into the safety pin slots respectively, and then put the special circlip into the circlip slot , then the wheel hub is fixed on the axle sleeve in the usual way, and this set of devices is exactly the pin circlip type fastening device of the automobile wheel.

Abstract

The invention provides a pin snap spring type fastening device of an automobile wheel, and relates to a device for fixing the wheel. According to the device, three square pins which are inserted intopin grooves at the interval of 120 degrees, so that a hub is fixed to a sleeve of an axle; meanwhile, insurance snap springs are clamped in snap spring grooves to clamp the lower portions of insurancepins, and then the upper portions of the pins are clamped through three small snap springs. The three insurance pins are used and protected through the special snap springs, so that high anti-shearing force and fastening capability are achieved; the pins cannot be disengaged, the driving safety is guaranteed, and the device is particularly suitable for small passenger cars, trucks and a part of medium-sized passenger cars.

Description

technical field [0001] The present invention relates to the combination of a wheel and a wheel axle, and more specifically, to a device for fixing the wheel. Background technique [0002] Usually, automobile wheel all is to adopt alignment pin, pin to be fixed on the axle sleeve pipe, and tire hub and sleeve pipe are fastened on the axle shaft with lock nut, lock washer and adjusting nut. This structure can operate normally within a certain period of time when the vehicle speed is low and the vibration is small. However, when the car runs for a long time, especially when the road surface is uneven and the load changes sharply, the axle bushing will bear a lot of impact. Once the shear force is too large, the pin will break, and the nut will loosen impact, the wheels and hubs will loosen. If the overhaul is not timely, or the driver is inexperienced, the tire will fall off with the wheel hub while the car is running. This is extremely dangerous. So people are seeking the ...
