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, this set of devices is exactly the snap ring type fastening device.

Abstract

The invention provides a jump-ring type fastener, relates to a device for fixing wheels, and aims at providing a pin jump ring type wheel fastener. The jump-ring type fastener is characterized in thatthree square pins which are respectively spaced by 120 DEG are inserted into a pin slot to fix a hub on a casing pipe of an axle while a relief jump ring is arranged into a jump ring slot to clamp the lower parts of the relief pins, and another three small jump rings clamp the upper part of the relief pins. As three relief pins are adopted while the special jump ring guards the pins, the jump-ring type fastener has strong shear resistance and fastening ability, and the pins does not come out, thus ensuring the driving safety, and being especially suitable for small passenger cars, trucks andsome medium-sized buses.

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 ...
