Abstract
The utility model discloses a rear axle for an electric wheeled wrecker, which comprises a thrust bottom plate assembly, an axle housing welding assembly, a door assembly, a left suspension bracket, a right suspension bracket, a transverse pull rod bracket and a cushion pad bracket. The thrust bottom plate assembly is obtained through welding a thrust bottom plate, an upper thrust plate, a lower thrust plate, a left thrust plate and a right thrust plate. An air duct is welded on the upper thrust plate. A welding cushion plate is respectively provided between the four thrust plates and the thrust bottom plate and between the upper thrust plate and the left and the right thrust plates. The thrust bottom plate, the upper thrust plate, the lower thrust plate, the left thrust plate and the right thrust plate are straight steel plates. The rear axle for electric wheeled wrecker has the following advantages: prevented cracking of body and welding seam, facilitated reasonable arrangement of stress, improved product quality, reduced material defect, reduced manufacturing trouble, reduced manufacturing cost, improved corporate image, and favourable comment of user.
Description
Technical field
The utility model relates to a kind of electric drive wheel wrecker back axle, especially relates to a kind of electric drive wheel wrecker back axle that is applicable to large surface mine.
Background technology
Present electric drive wheel wrecker back axle, conventional confguration by thrust bead assembly, axle housing be welded, door assembly, left and right sides suspended bearer, intermediate rod bearing, several parts of cushion rubber bearing are welded, wherein thrust bead assembly is by foundry goods thrust bead, thrust plate, the last thrust plate of bending, the left and right sides thrust plate and the air channel of bending are formed down.Its shortcoming is that casting quality is difficult to guarantee that the production and processing cost is high; Left and right sides thrust plate and last thrust plate are stressed unreasonable, and cracking phenomena often appears in its body and weld seam, and product design is inferior, reprocess the trouble difficulty.Also has a kind of improved structure, change thrust bead assembly wherein into upgrading thrust bead assembly, being specially foundry goods reinforced rib quantity reduces, left and right sides thrust plate and last thrust plate bending angle reduce, add the weldering reinforced rib on the thrust plate of the left and right sides, but processing is still complicated, and left and right sides thrust plate and last thrust plate and weld cracking phenomenon are still very frequent.These problems are perplexing people for these years together, bring tremendous loss for manufacturer and client.
The utility model content
The purpose of this utility model is to provide a kind of electric drive wheel wrecker back axle, to realize eradicating the cracking phenomena of body and weld seam, improves the quality of products; Process easier, reduce production costs, enhance productivity.
The technical solution of the utility model is: comprise that thrust floor pan assembly, axle housing are welded, door assembly, left and right sides suspended bearer, intermediate rod bearing, cushion rubber bearing, it is characterized in that, described thrust floor pan assembly is welded by four thrust plates of thrust base plate and upper and lower, left and right, on last thrust plate, be welded with the air channel, between four thrust plates and the thrust base plate and on be evenly equipped with composition backing between thrust plate and the left and right sides thrust plate, four thrust plates in described thrust base plate and upper and lower, left and right are flat plate.
Described axle housing is welded and is welded in thrust floor pan assembly rear portion.
Described door assembly is welded in the rear portion that axle housing is welded.
Described left and right sides suspended bearer with thrust floor pan assembly, axle housing be welded, the line of centers of door assembly is that symmetrical center line is welded on an axle housing of assembly both sides is welded.
Described intermediate rod bearing is welded in the axle housing top that is welded, described cushion rubber bearing with thrust floor pan assembly, axle housing be welded, the line of centers of door assembly is on axle housing that symmetrical center line is welded in intermediate rod bearing both sides is welded.
The utility model has been eradicated the cracking phenomena of body and weld seam, helps the reasonable distribution of stress, has improved product design; Reduce the material defective, reduced making trouble, reduced manufacturing cost; Also improve corporate image, obtained user's favorable comment.
