Description
Technical field
This utility model belongs to tractor field, is related to a kind of arrestment mechanism, and more particularly, to a kind of wheeled tractor is from increasing
Power disc type parking brake mechanism.
Background technology
At present, the high and medium power wheeled tractor parking brake mechanism of domestic production, mostly adopt multi-disc friction piece to brake,
Cam pressing handle structure.This parking brake mechanism volume is larger, and steering force is also larger；A pair of gear is needed to become from tractor
The little axis of cone of fast case is drawn, and part is more, and structure is also more complicated in addition it is also necessary to a single parking brake housing is arranged on and drags
Below machine drawing mechanism housing, cause the tractor road clearance to reduce, have impact on the walking performance of tractor.In order to make up this
Not enough it is necessary to develop a kind of compact conformation, manipulation is light, dismounting easily wheeled tractor self-energizing effort disk stopping brake machine
Structure, to meet the use requirement of tractor.
Utility model content
The purpose of this utility model is to provide a kind of compact conformation, easy to operate, transmission efficiency, safe and reliable
Wheeled tractor self-energizing effort disk parking brake mechanism.
The technical solution of the utility model is: wheeled tractor self-energizing effort disk parking brake mechanism, comprising: platen, steel
Ball, return spring, intermediate plate, friction plate, a bearing pin, brace, b bearing pin, main tie, a rocking arm, fixing bolt, arm-tie, rocking arm
Axle, b rocking arm, hand-made motion rocker arm；Return spring is articulated on the lug of platen, and friction plate is adjacent to platen and installs, two panels friction plate
Between equipped with an intermediate plate；In two braces, each brace two ends has a pin-and-hole respectively, and one end pin-and-hole is sold with a
Axle is connected with main tie, and other end pin-and-hole is connected with platen with b bearing pin；A rocking arm fixing bolt is contained on gear box casing, a
One end is connected with main tie, and the other end is connected with arm-tie, and the arm-tie other end is connected with b rocking arm with b bearing pin, b rocking arm and handss
Brake rocker arm is affixed with rocker arm shaft.
Platen circumference is provided with 4～6 water-drop-shaped ball-and-sockets, and two platens are installed face-to-face, and steel ball is contained in water-drop-shaped ball-and-socket
In.
This utility model is using can reach following beneficial effect: this wheeled tractor self energizing effort disk after technique scheme
Formula parking brake mechanism, using reliable, manipulates light, stroke is short, compact conformation, and arrangement is convenient.Compared with the like product of market,
This device transmission efficiency, manipulates laborsaving, preferably meets wheeled tractor parking brake requirements.
Brief description
Fig. 1 is the main structure diagram of this utility model wheeled tractor self-energizing effort disk parking brake mechanism；
Fig. 2 is the right side structural representation of this utility model wheeled tractor self-energizing effort disk parking brake mechanism.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.As shown in Fig. 1～2: wheeled tractor self energizing effort
Disc type parking brake mechanism, mainly by platen 1, steel ball 2, return spring 3, intermediate plate 4, friction plate 5, a bearing pin 6, brace 7, b
Bearing pin 8, main tie 9, a rocking arm 10, fixing bolt 11, arm-tie 12, rocker arm shaft 13, b rocking arm 14, hand-made motion rocker arm 15 form.Two
Individual platen 1 circumference has 4～6 water-drop-shaped ball-and-sockets, and two platens 1 are installed face-to-face, and steel ball 2 is contained in ball-and-socket, and return spring 3 is hung
It is connected on the lug of platen 1, friction plate 5 is adjacent to platen 1 and installs, equipped with an intermediate plate 4 between two panels friction plate 5；Each is oblique
Pull bar 7 two ends have a pin-and-hole respectively, and one end pin-and-hole is connected with main tie 9 with a bearing pin 6, the other end pin-and-hole b bearing pin 8 and pressure
Disk 1 connects；A rocking arm 10 is contained on gear box casing with fixing bolt 11, and a rocking arm 10 one end is connected with main tie 9, the other end with
Arm-tie 12 connects, and arm-tie 12 other end is connected with b rocking arm 14 with b bearing pin 8, b rocking arm 14 and hand-made motion rocker arm 15 and rocker arm shaft 13
Affixed.
During using self-energizing effort disk parking brake mechanism, pulling hand-made motion rocker arm 15, driving rocker arm shaft 13 to rotate, thus carrying
Dynamic b rocking arm 14 rotates；Pull a rocking arm 10 to be rotated up by arm-tie 12, pull up main tie 9, now by two oblique pulls
Bar 7 drives platen 1 to rotate, and steel ball 2 rolls so that platen 1 moves axially on water-drop-shaped ball-and-socket inclined-plane, pressing friction piece 5 He
Intermediate plate 4, produces brake force.When unclamping hand-made motion rocker arm 15, b rocking arm 14 grade part all loosens, and returns in situ, friction plate 5 pine
Open.
This wheeled tractor self-energizing effort disk parking brake mechanism is directly installed in the little axis of cone of change speed gear box, can be used as independent
Module is chosen to install.Compared with prior art, this device transmission efficiency, manipulates laborsaving, and it is wheeled dilatory preferably to meet
Machine parking brake requirements.
