It is fixed with pinion gear by small bearing and big bearing, pinion gear one end is connected with spring, tight by bevel gear box back-cover on spring
Close fit has a gear box cover and bevel gear, bevel gear box by bolt sleeve on bevel gear, among rack case steering block side according to
Secondary tight fit has nylon block, rubber ring, tightening that plug, disk spring, tightening is pushed to push piece and rack case back-cover, the rack case back of the body
It covers end and is fixed with screw bolt and nut, rack case both ends are socketed with oilless bearing, oil sealing and clamp spring, the setting of clamp spring side successively
There are taper gasket, rack both ends to pass sequentially through bolt and be fixed with limiting steering block and drag link mounting base.
As a preferred technical solution of the present invention, rack case and bevel gear box are all made of aluminium alloy and are made, compared to general
For logical metal, quality is light and inexpensive, realizes the lightweight of the present invention.
As a preferred technical solution of the present invention, limiting steering block and rack both ends offer lockpin hole, and lock
It is fitted close between pin hole and lock pin, realizes the imporosity of the present invention.
As a preferred technical solution of the present invention, butterfly spring is composed in series by several butterfly springs, and butterfly
Spring surface makees zinc-phosphatization and applies oil processing, improves anti-pressure ability, and realize good abrasion and corrosion resistance, extends device
Service life.
As a preferred technical solution of the present invention, the side of bevel gear box vertical tooth rack case is connected with bevel gear, cone
Gear box cover is connected on gear, being fitted close by bolt on gear box cover has bevel gear box back-cover, is convenient for and outside turns to
It is rotatablely connected between disk.
The advantageous effect that is reached of the present invention is：The present invention is a kind of light-weighted tooth sector rackwork, by making
With bevel gear to meeting arrangement demand after being rotated by 90 ° the input shaft of rack and pinion mechanism, compact overall structure uses aluminium
Alloy shell overall structure lighter in weight；And rack case and bevel gear box are all made of aluminium alloy and are made, very light weight, on common in-vehicle
It is to be manufactured by metal；In contrast, the present invention more lightweight, entire mechanism assembles up, compact-sized, gives light-weight design
More preferably effect is brought, keeps user more convenient to use, has adapted to the market demand.
