Slewing journal structure of dune buggy

Abstract

The invention discloses a knuckle pivot structure of a dune buggy and comprises an upper bulb holder, a lower bulb holder, a knuckle pivot, a bulb winch, a bulb shaft, two steering connectors that arearranged on the knuckle pivot and a bulb reaming orifice; the invention is characterized in that a ring slot is arranged on the bulb shaft; open slots are arranged on the two steering connectors andin the axes direction of the bulb reaming orifice, and the open slots are communicated with the bulb reaming orifice; a locking orifice is arranged on the knuckle pivot and communicated with the bulbreaming orifice, and a locking bolt is arranged inside the locking orifice; the locking bolt is used for limiting in coordination with the ring slot on the bulb shaft. The knuckle pivot of the invention is favorable to the assembly and the substitution of upper and lower cross arms as well as upper and lower bulb winches; the invention can implement disassembly, assembly and substitution conveniently without need to disassemble the related peripheral parts like the knuckle pivot, a driving shaft and a brake, etc., greatly reduces disassembly workload and provides extraordinarily convenient using; the invention can reduce the space size of the knuckle pivot assembly, is convenient for the installation and arrangement of related parts as well as disassembly and assembly.

Description

technical field [0001] The invention relates to an auxiliary steering part of a beach car, in particular to a steering knuckle structure of the beach car which is easy to disassemble. Background technique [0002] In the ATV with double wishbone structure in the prior art, the upper and lower wishbone are respectively connected with the upper and lower wishbone ball joints, and ball joints etc. are arranged in the upper and lower wishbone joints. The cross arm ball seat is respectively connected with the two connecting supports of the steering knuckle, and the upper and lower cross arms, the upper and lower cross arm ball seats and the steering knuckle are connected together to achieve the steering function. However, around the steering knuckle, especially around the connection between the steering knuckle and the upper and lower wishbone ball sockets, there are many components, such as transmission shafts, brakes, hubs, etc., due to the limitation of the installation positi...

AI Technical Summary

Problems solved by technology

However, around the steering knuckle, especially around the connection between the steering knuckle and the upper and lower wishbone ball sockets, there are many components, such as transmission shafts, brakes, hubs, etc., due to the limitation of the installation position of each component, and Due to the limitation of operating space, it is very inconvenient when assembling and replacing the upper and lower ball joints and the upper and lower cross arms. Usually, the steering knuckle, drive shaft, brake and other related surrounding components must be disassembled before the upper and lower cross arms can be installed. The lower ball joint and the upper and lower cross arms are disassembled for maintenance, inspection and replacement, etc.

Obviously, when assembling and replacing the upper and lower ball hinges and the upper and lower cross arms of the ATV with double wishbone structure in the prior art, there is a large disassembly workload and inconvenient disassembly, which is not conducive to the maintenance, inspection and replacement of parts. etc.; at the same time, the size of related components is relatively large, which makes the weight and volume of the steering knuckle larger, consumes more materials, and increases the overall weight of the ATV.
