Abstract

The utility model belongs to the technical field of the automobile shock absorber technique and specifically relates to a u type festival fork, including outer cylinder, steel sleeve pipe, u type lower festival fork, the bottom of outer cylinder is fixed with the steel sleeve pipe, adopts welded connection between steel sleeve pipe's up end and the outer cylinder, and steel sleeve pipe's bottom is fixed with u type lower festival fork, and the opening of u type lower festival fork sets up downwards, adopts welded connection between the top of u type lower festival fork and the steel sleeve pipe's lower terminal surface. Compared with the prior art, the utility model, the outer cylinder of shock absorber and u type lower section fork adopt steel sleeve pipe welded connection, have simplified the product structure, wholly subtract heavy about 500g, welded connection has guaranteed product strength, simultaneously, has removed the location assembly process of cast aluminium lower section fork from, has also reduced the supply chain of production material.

Description

U-shaped joint fork

Technical Field

The utility model belongs to the technical field of the automobile shock absorber technique and specifically relates to a u type festival fork.

Background

The structure of a front axle strut assembly commonly applied to a double-wishbone type vehicle suspension at present is generally composed of the following main components: the device comprises a spiral spring, an upper mounting seat assembly, a shock absorber assembly and a cast aluminum lower yoke. Wherein, the upper mounting seat assembly is a connecting element and mainly used for connecting the frame; the spiral spring is a buffer element and mainly used for relieving the influence of impact from the ground on the vehicle body; the shock absorber assembly is a shock absorption element and mainly has the main function of consuming the energy of the vibration of the suspension by using the resistance of the self oil flow; the cast aluminum lower yoke is also a connecting element and mainly used for connecting the axle.

The cast aluminum lower section fork of the front axle sliding column assembly structure is assembled with the shock absorber assembly through three parts, namely a bolt, a nut and a positioning bracket on an outer cylinder barrel of the shock absorber assembly, so that the final delivery and delivery state of the front axle sliding column assembly is achieved. However, the structure is complex, the production and assembly cost is high, and the supply chain of production materials is high.

Therefore, a u-shaped joint fork is needed to be designed, so that the structure is simplified, the production cost is reduced, and the supply chain of production materials is reduced while the product strength is ensured.

Disclosure of Invention

The utility model aims at overcoming prior art's not enough, providing a u type festival fork, when guaranteeing product strength, simplifying the structure, reduction in production cost reduces the supply chain of production material.

In order to achieve the purpose, the utility model relates to a u type festival fork, including outer cylinder, steel sleeve pipe, the lower festival fork of u type, the bottom of outer cylinder is fixed with the steel sleeve pipe, adopts welded connection between steel sleeve pipe's up end and the outer cylinder, and steel sleeve pipe's bottom is fixed with the lower festival fork of u type, and the opening of the lower festival fork of u type sets up downwards, adopts welded connection between the top of the lower festival fork of u type and the lower terminal surface of steel sleeve pipe.

The connection strength between the outer cylinder barrel and the steel sleeve is not less than 28 KN.

The connection strength between the steel sleeve and the u-shaped lower yoke is not less than 28 KN.

Compared with the prior art, the utility model, the outer cylinder of shock absorber and u type lower section fork adopt steel sleeve pipe welded connection, have simplified the product structure, wholly subtract heavy about 500g, welded connection has guaranteed product strength, simultaneously, has removed the location assembly process of cast aluminium lower section fork from, has also reduced the supply chain of production material.

Drawings

Fig. 1 is a schematic view of the present invention.

Detailed Description

The invention will now be further described with reference to the accompanying drawings.

Referring to the figure 1, the utility model relates to a u type festival fork, including outer cylinder, steel sleeve pipe, u type lower section fork, the bottom of outer cylinder 3 is fixed with steel sleeve pipe 1, adopts welded connection between steel sleeve pipe 1's up end and the outer cylinder 3, and steel sleeve pipe 1's bottom is fixed with u type lower section fork 2, and the opening of u type lower section fork 2 sets up downwards, adopts welded connection between u type lower section fork 2's the top and the lower terminal surface of steel sleeve pipe 1.

The utility model discloses in, joint strength between outer cylinder 3 and the steel sleeve pipe 1 is greater than or equal to 28 KN. The connection strength between the steel casing 1 and the u-shaped lower yoke 2 is not less than 28 KN. The welded connection can ensure the strength and performance of the product.

The utility model discloses when the assembly, the material only has steel sleeve pipe 1, reduces to one by original three material, has reduced the complexity of production material, has reduced the supply chain of material.

The utility model discloses the assembly, can go on at outer cylinder welding production line, under the condition that the volume production frock is taken one's place, increase the welding assembly that U type festival fork can be accomplished to welding line one, cancelled the location assembling process of festival fork under the complicated cast aluminium, though newly-increased welding process, but both comparatively speaking, the welding process cost is lower also more save time, more has the high efficiency of production, has also reached the product simultaneously and has subtract heavy effect.

The utility model discloses the outer cylinder and the u type of shock absorber lower section fork adopt steel sleeve pipe welded connection, have simplified the product structure, wholly subtract heavy about 500g, and welded connection has guaranteed product strength, has equal performance on the front suspension of vehicle. Meanwhile, the positioning and assembling process of the cast aluminum lower yoke is omitted, and the supply chain for producing materials is reduced.
