Abstract

The utility model discloses a pillar assembly, including last pillar, lower pillar, go up the upper end of pillar and install the bearing, it passes through bearing and steering shaft to go up the pillar, the bottom of pillar is provided with the mount pad down, mount pad and connected to the frame, its characterized in that the lower extreme punching press of going up the pillar has a plurality of riveting point, the riveting point evenly sets up along the circumferencial direction, it passes through riveting point and pillar interference pressfitting down to go up the pillar, the interference magnitude of going up pillar and pillar down satisfies conquassation power 1500 and gives 2500N. The utility model discloses with traditional centre carry out the injecting glue with the plastic cover and be connected and compare, reduced manufacturing cost, improved production efficiency, during the installation, with the steering spindle and the bearing assembly of steering wheel, with the mount pad install on the frame can, simple to operate is swift.

Description

Protective pipe assembly

Technical Field

The utility model relates to an improvement invention of an automobile steering system, in particular to a protective tube assembly.

Background

The automobile steering system is used for controlling the running direction of an automobile, the upper end of a steering shaft of the steering system is connected with an automobile square plate, the lower end of the steering shaft is connected with a steering intermediate shaft, the steering shaft transmits force applied to the steering wheel to the steering intermediate shaft, the force is transmitted to a steering gear through the steering intermediate shaft, and the steering gear drives wheels to steer, so that the automobile is steered. The steering shaft is arranged on the frame through the protective pipe assembly; the existing protective pipe assembly has the problems of low driving safety coefficient and high installation difficulty.

SUMMERY OF THE UTILITY MODEL

In view of the technical problem who exists among the background art, the utility model aims at providing a factor of safety height, be convenient for fortune pillar assembly of installation.

In order to solve the technical problem, the utility model discloses a following technical scheme: the protective pipe assembly comprises an upper protective pipe and a lower protective pipe, wherein a bearing is mounted at the upper end of the upper protective pipe, the upper protective pipe is connected with a steering shaft through the bearing, a mounting seat is arranged at the bottom of the lower protective pipe, and the mounting seat is connected with a frame.

The upper protection pipe is welded with a wire harness support, and the wire harness support is provided with a through hole for a wire harness to pass through.

The utility model discloses an go up the pillar through the riveting with pillar interference pressfitting down to interference magnitude satisfies conquassation power 1500 + 2500N, carries out the injecting glue with the plastic cover with traditional centre and is connected and compare, has reduced manufacturing cost, has improved production efficiency, during the installation, with the steering spindle and the bearing assembly of steering wheel, with the mount pad install on the frame can, simple to operate is swift.

Fig. 3 is an enlarged view of fig. 2A according to the present invention.

Detailed Description

The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings. This kind of pillar assembly, including last pillar 1, lower pillar 3, bearing 5 is installed to the upper end of going up the pillar, go up the pillar and pass through the steering shaft connection of bearing and steering wheel, it has wire harness support 2 to go up pillar skin weld, wire harness support has the through-hole 6 that supplies the pencil to pass, and wire harness support 2 arranges the pencil in order, and the pencil is in disorder not only influences the installation, has had the potential safety hazard moreover. The bottom of the lower protection tube 3 is provided with a mounting seat 4, the mounting seat is connected with a vehicle frame and can be connected by a locking bolt, the lower end of the upper protection tube 1 is punched with a plurality of riveting points 7, in the embodiment, the riveting points 7 are eight, the riveting points 7 are uniformly arranged along the circumferential direction, the upper protection tube 1 is in interference press fit with the lower protection tube 3 through the riveting points, because the riveting points 7 are uniformly arranged, the bearing force of each angle of the upper protection tube 1 and the lower protection tube 3 is the same, the interference magnitude of the upper protection tube 1 and the lower protection tube 3 meets the crushing force of 1500 and 2500N, if the interference magnitude exceeds the range, the safety coefficient is greatly reduced, if the interference magnitude of the upper protection tube and the lower protection tube is too low, the upper protection tube is easy to move downwards relative to the lower protection tube due to slight impact force, if the interference magnitude is too high, the significance is lost, and when a vehicle collides, the upper protection tube still keeps still not moving relative to the lower protection tube, the impact force is not cushioned, so that the driver is severely impacted. The utility model discloses to go up pillar, pillar and bearing assembly down, when the installation, with the steering spindle and the bearing assembly of steering wheel, with the mount pad through locking bolt installation on the truck frame can, simple to operate is swift.

Claims

1. A protective pipe assembly comprises an upper protective pipe and a lower protective pipe, wherein a bearing is mounted at the upper end of the upper protective pipe, the upper protective pipe is connected with a steering shaft through the bearing, a mounting seat is arranged at the bottom of the lower protective pipe, and the mounting seat is connected with a frame.

2. The grommet assembly as set forth in claim 1, wherein said upper grommet is welded with a harness support having a through hole for passing a harness therethrough.
