Description

A kind of hand inertial one brake gear
Technical field
The present invention relates to a kind of brake gear, specifically a kind of hand inertial one brake gear.
Background technology
Trailer is connected with tractor by draw-gear, travelled by tractor traction, when tractor brakes or speed change When, trailer can produce shock due to the effect of inertia and tractor above, especially when trailer quality is bigger, it is easier to produce Raw potential safety hazard.Have arranges brake gear on trailer, but structure is complicated and the interactive difference with tractor, using effect And it is bad.
Content of the invention
For the shortcoming overcoming above-mentioned prior art to exist, it is an object of the invention to provide a kind of hand inertial and integrally stop Car device, it can realize inertia brake and hand-operated brake, simple in construction, stable and reliable in work.
In order to solve the problems referred to above, the present invention by the following technical solutions: a kind of hand inertial one brake gear, it is special Levy and be, including draw bar link, draw bar, spring, master cylinder, hand brake device and reversing baffle plate, described draw bar link Being fixed on the left end of draw bar, the fixing hole that the right-hand member of draw bar passes through on fixed cover is connected with tune journey nut, adjusts journey nut The other end is connected with master cylinder by connecting rod, and fixed cover is fixed on trailer body, and draw bar can be relatively fixed about set sliding Dynamic, on draw bar, the left side of fixed cover is provided with spring, and described master cylinder is fixed on trailer body, master cylinder respectively with The wheel cylinder being arranged on wheel connects, and described hand brake device includes parking brake handle, parking brake latch hook, the lower end of parking brake handle Hinged with the fixed plate in master cylinder, parking brake handle passes through spindle nut near lower end position and rod hinge connection, parking brake latch hook Being arranged on parking brake handle, lower pressure parking brake latch hook can be with the fixed plate clamping in master cylinder, and described reversing baffle plate is half Annular, reversing baffle plate is hinged on trailer body, and rotating reversing baffle plate makes reversing baffle plate and draw bar coaxial, reverse gear shift board The right side of the shaft shoulder on draw bar.
Further: to be additionally provided with disk spring and limited block at the spindle nut of brake lever, limited block limits hand brake lock The rotational angle of hook.
The invention has the beneficial effects as follows:
1st, during towing vehicle travels as to slow down or to stop brake when, owing to principle of inertia draw bar link can be towards Adjusting journey nut direction to move, adjusting journey nut to be slowed down by connecting rod driving brake master cylinder action executing or brake, master cylinder drives Wheel cylinder realizes slowing down or brake.This set effectively prevent the shock to tractor in moderating process for the trailer, and The dynamics of tractor slowing-down brake is by effect of inertia to master cylinder, and dynamics is bigger, and inertia is bigger, and master cylinder is by being used to Property power bigger, the braking strength of master cylinder automatically adjusts according to brake inertia, it is ensured that slowing down or brake flat of trailer Stability and the synchronism with tractor.
2nd, when needs are moveed backward, reversing baffle plate rotates to and draw bar coaxial state, and reverse gear shift board is on draw bar The right side of the shaft shoulder, the active force of reversing is directly delivered on reversing baffle plate by the shaft shoulder of draw bar, and reversing baffle plate directly will reversing Active force act on tractor, it is achieved car-backing function, in reversing process axis of traction will not transmitting forces total to brake Impact reversing on pump.
3rd, needing to pull parking brake handle drives master cylinder to work during parking brake, manual depression parking brake latch hook is stuck in brake simultaneously In the fixed plate of master cylinder, at spindle nut, there are butterfly spring, limited block can keep stablizing of braking state.
4th, adjust journey nut can arbitrarily adjust the movement travel of master cylinder within the specific limits, thus control master cylinder The dynamics of brake.
Brief description
The present invention is described further with example below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the structural representation of the reversing baffle plate of the present invention;
In figure: 1 draw bar link, 2 shaft shoulders, 3 draw bars, 4 springs, 5 fixed covers, 6 tune journey nuts, 7 parking brake handles, 8 hands Stop latch hook, 9 master cylinder, 10 trailer bodies, 11 reversing baffle plates, 12 connecting rods, 13 fixed plates, 14 spindle nut.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of hand inertial one brake gear, including draw bar link the 1st, draw bar the 3rd, spring is the 4th, Master cylinder the 9th, hand brake device and reversing baffle plate 11, described draw bar link 1 is fixed on the left end of draw bar 3, draw bar 3 The fixing hole that right-hand member passes through on fixed cover 5 is connected with tune journey nut 6, and the other end adjusting journey nut 6 is total with brake by connecting rod 12 Pump 9 connects, and fixed cover 5 is fixed on trailer body 10, and draw bar 3 can be relatively fixed set 5 and horizontally slip, fixing on draw bar 3 Set 5 left side be provided with spring 4, described master cylinder 9 is fixed on trailer body 10, master cylinder 9 respectively be arranged on wheel Wheel cylinder on son connects, and described hand brake device includes parking brake handle the 7th, parking brake latch hook 8, the lower end of parking brake handle 7 with stop Fixed plate 13 on car master cylinder 9 is hinged, and parking brake handle 7 is hinged with connecting rod 12 near lower end position, and parking brake latch hook 8 passes through rotating shaft spiral shell Female 14 are arranged on parking brake handle 7, and lower pressure parking brake latch hook 8 can be with fixed plate 13 clamping in master cylinder 9, described reversing Baffle plate 11 is semi-circular shape, and reversing baffle plate 11 is hinged on trailer body 10, and rotating reversing baffle plate 11 makes reversing baffle plate 11 and lead Draw bar 3 coaxial, the right side of the shaft shoulder 2 that reversing baffle plate 11 is stuck on draw bar 3.
Being additionally provided with disk spring and limited block at the spindle nut 14 of brake lever 7, limited block limits turning of parking brake latch hook 8 Dynamic angle.
The present invention is not limited solely to above-described embodiment.
