Background technology
At present, most of cars all adopt the structure of engine behind front wheel before driving, and propons is as the drive axle of automobile, and back axle is as follow-up bridge, and this moment, back axle often played the effect of carrying.And the back axle crossbeam is as the structure of automobile axle outbalance, and it is particularly crucial that the stability of its connection structure and every performance just seem.And at present, the back axle crossbeam is often only played a supporting role, and some back axle parts need be connected on the back axle by more corresponding connection structures, makes and complex installation process, also is unfavorable for the integrated of automobile simultaneously.
Patent Office of the People's Republic of China on February 7th, 2007 announced the utility model patent that name is called automobile axle, and notification number is CN2866205Y.This back axle comprises curb girder, the back rest, body contact support and prenex connecting rod rack; Curb girder has two, connects by front-axle beam therebetween; Two curb girders are connected with the back rest respectively; The body contact support is provided with mounting groove, is located at the end of curb girder; Prenex connecting rod rack is located in the mounting groove of body contact support; Be characterized in, the integrated formation of body contact support and curb girder, the body contact support is made of the cavity of curb girder end, and the inboard of curb girder is provided with notch at the position near the end; Prenex connecting rod rack is a frame shape, is embedded in described notch.This back axle lacks the connection structure of corresponding part and device, and the curb girder and the back rest only play the carrying effect, is not easy to other Unit Installation and fixes, and does not arrive certain integrated effect.
Summary of the invention
The purpose of this utility model is to solve traditional back axle crossbeam and lacks corresponding connection structure, being not easy to part installs and automobile integrated problem, provide a kind of part of being convenient to install, need not outsidely connect support, realized automobile integrated automobile axle crossbeam assembly.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of automobile axle crossbeam assembly, comprise the back axle cross-beam body, described back axle cross-beam body two ends are equipped with mandrel and the spring carrying block that is used to be connected the back axle leaf spring, are connected with parking brake assembly, brake caliper, wheel hub tape spool on the described mandrel in turn and hold assembly, brake disc and dust boot.The utility model is provided with spring carrying block at back axle crossbeam two ends, in order to the back axle leaf spring to be installed, mandrel is set simultaneously, hold assembly, brake disc and dust boot by mandrel connection parking brake assembly, brake caliper, wheel hub tape spool, make things convenient for above Unit Installation location, realized the integrated of back axle crossbeam simultaneously.
As preferably, the cover that described mandrel one end is provided with in order to connect the back axle cross-beam body heals up, the other end is provided with stepped shaft, and the bottom of described stepped shaft is provided with the attachment face that is used to install parking brake assembly, and mandrel middle part outwards convexes to form in order to the fixing V-shaped rest of brake caliper.Cover heals up being connected and the location in order to mandrel and crossbeam, attachment face is in order to the location and parking brake assembly is installed, and realizes that by stepped shaft the wheel hub tape spool holds the level installation of assembly, brake disc and dust boot, V-shaped rest Stability Analysis of Structures, the intensity height is used for the location and brake caliper is installed.
As preferably, described back axle cross-beam body is a hollow circular-tube.When hollow circular-tube satisfies requirement of strength, reduce part assembly quality, promote the lightweight of automobile.
As preferably, the medial surface welding of healing up of the cover of the described mandrel end fit with the back axle cross-beam body that heals up, described back axle cross-beam body end edge and cover forms branch weld seams such as three sections.Heal up and the beam-end edge carries out soldering at cover, and welding forms the trisection weld seam, increase the Joint strenght of mandrel and crossbeam, the junction of balance stressed improves connection stability simultaneously.
As preferably, described mandrel is provided with the loss of weight groove.The loss of weight groove has alleviated part quality, realizes lightweight, and the installation for part simultaneously provides sufficient space.
The utility model is provided with mandrel at back axle cross-beam body two ends, structure by mandrel provides the location and is connected for parking brake assembly, brake caliper, wheel hub tape spool hold assembly, brake disc and dust boot, spring carrying block is set simultaneously in order to leaf spring to be installed, realizes the integrated of back axle crossbeam.
