Abstract
A medium-low-power horticultural tractor disc brake and tail-end transmission mechanism comprises a driving shaft, a brake tail-end shell, a driven gear, a driving gear shaft, a friction piece, a partition plate, a platen, a platen base, a steel ball, a poking shaft and a crank. The platen base is connected with the brake tail-end shell. The friction piece, the partition plate, the platen and the steel ball are sequentially located between the brake tail-end shell and the platen base. The partition plate and the friction piece are arranged at an interval. The end face of one side of the platen is adjacent to the friction piece. A cone spherical groove is machined in the end face of the other side of the platen and corresponds to a spherical groove in the platen base. The steel ball is located in the portions, between the platen and the platen base, of the grooves. The poking shaft is supported to the platen base, one end of the poking shaft is welded to the crank, and the other end of the poking shaft is opposite to the machining face of the groove in the platen. The driving gear shaft is simply supported to a rear axle shell and the brake tail-end shell, one end of the driving gear shaft is connected with a spline inside a rear axle differential half shaft gear, and the other end of the driving gear shaft is connected with a spline inside the friction piece. The driven gear is meshed with the driving gear shaft and connected with the driving shaft. The driving shaft is simply supported on the rear axle shell and the brake tail-end shell.
Description
Technical field
The utility model belongs to trac. field, relates to a kind of middle low power midget-garden tractor disc type brake and end driving mechanism.
Background technology
At present, the middle low power wheel-tire tractor that China produces, its brake equipment and end driving mechanism are generally absolute construction.Brake equipment generally adopts shoe brake and plate disc brake.These two kinds of drgs are generally and comprise the Separate Brake assembly of braking housing, complicated structure, and number of parts is more, and its braking platen size is larger, is not suitable with the required narrow wheelspan of present stage midget-garden tractor, undersized market demands.
Utility model content
The purpose of this utility model be to provide a kind of compact conformation, rationally distributed, brake smooth-going, operation failure-free middle low power midget-garden tractor disc type brake and end driving mechanism.
The utility model adopts following technical scheme to realize above-mentioned purpose: middle low power midget-garden tractor disc type brake and end driving mechanism, comprise axle drive shaft, braking end housing, driven gear, driving gear shaft, friction lining, dividing plate, platen, platen seat, steel ball, pulling axis, crank; Between platen seat and braking end housing, with dowel bolt, connect, and be fixed on back axle with overbolt; Friction lining, dividing plate, platen, steel ball are successively in the cavity of braking between end housing and platen seat, dividing plate and friction lining interval are arranged, platen one side end face is adjacent with friction lining, on opposite side end face, be processed with one group of conisphere connected in star, corresponding with ball recess on platen seat, steel ball is arranged in the groove between platen and platen seat; Pulling axis is supported on platen seat, one end and crank welding, and one section of plane of other end processing, relative with the Pocket Machining face on platen; Driving gear shaft is by bearing freely-supported on rear axle housing body and braking end housing, and one end is connected with female splines on rear axle differential side gear, and the other end is connected with the female splines on friction lining; Driven gear and driving gear shaft engagement, be connected with axle drive shaft by spline, and axle drive shaft passes through bearing freely-supported on rear axle housing body and braking end housing.
Between friction lining and braking end housing, dividing plate, platen, leave mutually 0.2 ± 0.02mm gap.
The utility model can reach following good effect after adopting technique scheme: compact conformation, brake smooth-going, operation is reliable.Adopt after this mechanism, tractor braking device and end driving mechanism are positioned at same housing, simplify the structure, and size reduction, make brake equipment and end drive mechanism compacter, can adapt to the required narrow wheelspan of middle low power midget-garden tractor, undersized machine requirement completely.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model middle low power midget-garden tractor disc type brake and end driving mechanism.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figure 1, middle low power midget-garden tractor disc type brake and end driving mechanism, braking end housing 2 is fixed by bolts on back axle 5, platen seat 9 is spirally connected with braking end housing 2, in friction lining 6, dividing plate 7, platen 8, the cavity of steel ball 10 between braking end housing 2 and platen seat 9,2 dividing plates 7 and 3 friction lining 6 intervals are arranged, platen 8 one side end faces are adjacent with friction lining 6, on opposite side end face, be processed with one group of conisphere connected in star, corresponding with ball recess on platen seat 9, steel ball 10 is arranged in the groove of 9 of platen 8 and platen seats; Between friction lining 6 and braking end housing 2, dividing plate 7, platen 8, leave mutually 0.2 ± 0.02mm gap; Pulling axis 11 is supported on platen seat 9, one end and crank 12 welding, and the other end is processed a plane, relative with the Pocket Machining face on platen 8; Driving gear shaft 4 is by bearing freely-supported on back axle 5 housings and braking end housing 2, and one end is connected with the female splines on back axle 5 differential side gears, and the other end is connected with the female splines on friction lining 6; Driven gear 3 and driving gear shaft 4 engagements, be connected with axle drive shaft 1 by spline after deceleration, and the transmission of power that back axle biography is come is to axle drive shaft, and band motor car wheel, makes complete machine motion.
When complete machine need to be braked, pull crank 12 to make pulling axis 11 rotations, promote platen 8 rotations, steel ball 10 is moved on the conical surface of platen 8, gap between successive elimination friction lining 6 and braking end housing 2, dividing plate 7, platen 8, friction lining 6 is pressed on braking end housing 2, and the friction moment of generation has stoped with the driving gear shaft 4 of friction lining 6 spline joints and has been rotated further, thereby realizes tractor braking.
The utility model compact conformation, brake smooth-going, operation is reliable.Brake equipment and end driving mechanism are positioned at same housing, simplify the structure, and make brake equipment and end drive mechanism compacter, adapt to the required operating needs of current middle low power midget-garden tractor completely.
