Abstract
The utility model discloses a dead rear axle for automobiles, which comprises a rear axle tube. A left rear hub shaft seat and a right hub shaft seat are upwardly symmetrically disposed on two sides of the rear axle tube, a left steel plate spring seat, a right steel plate spring seat, a left rear shock absorber lower seat and a right rear shock absorber lower seat are sequentially symmetrically arranged on the rear axle tube at positions close to the left rear hub shaft seat and the right hub shaft seat, and the left steel plate spring seat and the right steel plate spring seat are fixedly connected to the upper side of the rear axle tube via an arc-shaped plate matching with the outer arc surface of the rear axle tube. The dead rear axle has the advantages that the dead rear axle is simple in structure, can reduce production cost of an integral automobile and meets requirements of commercial functions, the left steel plate spring seat and the right steel plate spring seat are fixedly connected to the upper side of the rear axle tube so as to improve lateral toppling stability of the integral automobile and reduce cost of the integral automobile on the premise of guaranteeing safety, and the left rear hub shaft seat and the right hub shaft seat are disposed on the two sides of the rear axle tube so as to meet requirements on the strength of longitudinal force limit and lateral force limit born by rear wheels during braking and turning and assuredly meet requirements of integral strength and reliability of a rear axle shell.
Description
Technical field
The utility model relates to automobile axle, especially relates to the on-propelled back axle that is used for automobile.
Background technology
At present, domestic a lot of utility vans (MPV) rear-suspension system is generally many connecting rods coil spring independent suspension structure, not only complex structure, cost height, and inapplicable commercial cargo-carrying requirement.
The utility model content
The purpose of this utility model is to provide a kind of on-propelled back axle that is used for automobile of simple in structure, train stability safety.
For achieving the above object, the utility model can be taked following technical proposals:
The on-propelled back axle that is used for automobile described in the utility model, it comprises the back bridge tube, upwards be symmetrically arranged with left and right rear-wheel hub axle bed in bridge tube both sides, described back, near left and right rear-wheel hub axle bed back bridge tube on be symmetrically arranged with following of left and right spring perch and left and right rear shock absorber successively.
Described left and right spring perch is connected in the top of described back bridge tube by the arc that matches with back bridge tube extrados.
Advantage of the present utility model is simple in structure, can reduce the car load productive costs, satisfies commercial functional requirement.The utility model is applicable to take advantage of and carries leaf spring structure behind the formula vehicle body on-propelled.Axle housing with integrally-built back bridge tube substitutes punching press, is welded has improved intensity and intensity; Left and right sides spring perch is connected in the top of back bridge tube, improved the height at back axle suspension roll center, reduced the rolling moment arm length of rear axle sprung weight, when the car body tempo turn, improved the car load roll stability, therefore, adopt back described in the utility model bridge construction can cancel the Panhard rod of rear suspension, reduced integral vehicle cost under the premise that security is guaranteed; The left and right sides rear-wheel hub axle bed that is arranged on bridge tube both sides, back has guaranteed to connect the functions of use of trailing wheel on the one hand, the limit longitudinal force that trailing wheel bears in braking and when turning and the requirement of strength of side force have been satisfied on the other hand, since the axis that is placed on the hind axle on the rear-wheel hub axle bed of the left and right sides be positioned at the back axle tube's axis directly over, the ingenious force-bearing situation of having optimized back bridge tube trim directions has guaranteed the bulk strength and the reliability requirement of rear axle housing body.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, the on-propelled back axle that is used for automobile described in the utility model, it comprises back bridge tube 1, upwards be symmetrically arranged with left and right rear-wheel hub axle bed 2,3 in bridge tube 1 both sides, described back, near left and right rear-wheel hub axle bed 2,3 back bridge tube 1 on be symmetrically arranged with left and right spring perch 4,5 and left and right rear shock absorber successively following 6,7.Described left and right sides spring perch 4,5 is connected in the top of described back bridge tube 1 by the one group of arc that matches with back bridge tube 1 extrados.
For strengthening its rigidity and intensity, back bridge tube 1 adopts solid drawn pipe, has substituted the axle housing that original punching press is welded; Left and right sides spring perch 4,5 is welded on the top of described back bridge tube 1 by one group of arc, layout after the steel spring that is installed on it is positioned on the bridge tube 1, improved the height at back axle suspension roll center, thereby reduced the rolling moment arm length of rear axle sprung weight, vehicle body has improved the car load roll stability when tempo turn, therefore after adopting back of the present utility model bridge construction, can cancel the Panhard rod of rear suspension, reduce integral vehicle cost under the premise that security is guaranteed; The left and right rear-wheel hub axle bed 2,3 of back bridge tube 1 both sides adopts forging formula structure, be welded on the both sides of back bridge tube 1 then, guaranteed to connect the functions of use requirement of trailing wheel so on the one hand, also satisfied the limit longitudinal force that trailing wheel bears and the requirement of strength of side force on the other hand under braking and turning operating mode; Since the axis that is placed on the hind axle on the left and right rear-wheel hub axle bed 2,3 be positioned at back bridge tube 1 axis directly over, the ingenious force-bearing situation of having optimized back bridge tube 1 trim directions, thus guaranteed the bulk strength and the reliability requirement of rear axle housing body.
Claims (2)
1. on-propelled back axle that is used for automobile, it is characterized in that: it comprises back bridge tube (1), upwards be symmetrically arranged with left and right rear-wheel hub axle bed (2,3) in bridge tube (1) both sides, described back, near left and right rear-wheel hub axle bed (2,3) back bridge tube (1) on be symmetrically arranged with left and right spring perch (4,5) and following of left and right rear shock absorber (6,7) successively.
