Abstract
The utility model relates to an improved rear axle housing for motor vehicle chassis, which comprises a rear axle housing body and axle sleeves of the left and right ends, and is characterized in that: the rear axle housing body and the axle sleeves are in a split type structure, an integrated structure which is formed by inner and outer screw fastening is arranged between the rear axle housing body and the axle sleeves; the joint of screw fastening is provided with at least a holding screw for fastening. Compared with the prior art, the inner and outer screw fastening structure is adopted between the rear axle housing body of the entire rear axle and the axle sleeves, thereby when the axle sleeves are cracked, the rear axle housing body will not be out of service. The utility model has the advantages that: the maintenance is easy, the assembly and disassembly are convenient and speedy. Due to the rear axle housing body is unnecessary to be replaced, so the production and maintenance costs can be saved.
Description
Technical field
The utility model relates to a kind of self-propelled vehicle (as farm vehicle) chassis rear-axle casing of motor-vehicle chassis designing technique, particularly a kind of improvement type.
Technical background
Rear-axle casing is a vitals of motor-vehicle chassis assembly, the whole bridge of rear-axle casing generally comprises the formations such as axle tube at rear-axle casing body and two ends, the left and right sides, wherein generally be near bow plate holder (frame), to adopt to be welded into all-in-one-piece structure between axle housing and the two-semiaxle sleeve pipe, but whole bridge easy deformation in welding process, shortcoming such as crack, because the current mobility car is the farm vehicle ubiquity overweight phenomenon that overloads particularly, further causes the axle tube of back axle to rupture easily.In case the axle tube fracture will cause scrapping of whole rear-axle casing, strengthen the difficulty (needing the whole rear-axle casing of dismounting and change) of technical maintenance.
The utility model content
The purpose of this utility model is to overcome above-mentioned defective, thereby a kind of motor-vehicle chassis rear-axle casing of improvement type is provided, and makes guaranteeing on the high basis of rear-axle casing overall construction intensity, also have the dismounting maintenance easily, part replacement effect easily and efficiently.
The utility model is realized with following technical scheme: it comprises the axle tube at rear-axle casing body and two ends, the left and right sides, it is characterized in that rear-axle casing body and axle tube at first are to make split type structure, be between the two with internal and external threads spin (being spirally connected) constitute the structure of one, and be provided with at least one holding screw in the threaded connection place and carry out fastening.
Because the utility model will constitute between the axle tube of the rear-axle casing body of the whole bridge of back axle and the right and left the employing internal and external threads strong design that spins mutually, when axle tube generation fracture damage, the rear-axle casing body can not scrapped (still as excellent as before), need only screw off holding screw during maintenance, withdraw from (back-out) old sleeve pipe (screw-in) new casing of packing into, screwing holding screw gets final product, compared with the prior art, has maintenance easily, install and remove conveniently advantage, because of will the replacing of rear-axle casing body not scrapping, also can save manufacturing cost and maintenance cost.
Description of drawings
Fig. 1 is a kind of mounting structure scheme drawing of the utility model rear-axle casing.
Fig. 2 is the enlarged drawing of Fig. 1 at threaded connection place A.
Wherein: 1～axle tube (also claiming the back axle sleeve pipe), 2～holding screw, 3～threaded connection place, 4～bow plate holder (also claiming ride seat or steel plate holder), 5～rear-axle casing body.
The specific embodiment
With reference to accompanying drawing as can be known, rear-axle casing body 5 described in the utility model and axle tube 1 threaded connection place 3 between the two is to be positioned near the bow plate holder 4 of rear-axle casing.
Near the coupling end of the described axle tube 1 of this novel rear-axle casing is to make external thread structure, the coupling end of rear-axle casing body is to be positioned near the bow plate holder 4 at two ends, the left and right sides, and makes the cooperation (can be left and right hand thread is connected) that spins of female thread structure and axle tube.
Claims (2)
1, a kind of improvement type motor-vehicle chassis rear-axle casing, it comprises the axle tube (1) at rear-axle casing body (5) and two ends, the left and right sides, it is characterized in that rear-axle casing body (5) and axle tube (1) are to make split type structure, be to spin with internal and external threads to constitute the structure of one between the two, and (3) are provided with at least one holding screw (2) and carry out fastening in the threaded connection place.
2, motor-vehicle chassis rear-axle casing according to claim 1 is characterized in that described rear-axle casing body (5) and axle tube (1) threaded connection place (3) between the two is to be positioned near the bow plate holder (4) of rear-axle casing.
