Abstract
The utility model belongs to Hydraulic Elements, in particular to a kind of Retarder front cover.Multiple weight loss grooves (1-2) is circumferentially laid on the end face of front cover body (1), working chamber (1-4), bearing hole (1-6), oil sealing hole are respectively equipped on front cover body (1), working chamber is connected to oil sealing hole (1-7), oil sealing hole is connected to bearing hole, working chamber uses arc-shaped inner wall, throttle valve mounting hole (1-9) is equipped on the front cover body (1) of the position of corresponding working chamber minimum point and oil temperature detection device mounting hole, throttle valve mounting hole are connected to working chamber with oil temperature detection device mounting hole.Retarder front-cover structure is simple, by being circumferentially laid with multiple lightening holes on front cover body, by increasing the contact area with air, improve the heat-sinking capability of working chamber, by being equipped with throttle orifice on the front cover body of the position of corresponding working chamber minimum point, the mobility for increasing working fluid effectively improves the braking effect and service life of Retarder.
Description
Technical field
The utility model belongs to Hydraulic Elements, in particular to a kind of Retarder front cover.
Background technique
Due to the rapid development of automotive engineering and the continuous improvement of road conditions, the travel speed of automobile is generally improved, together
When some commercial vehicles large-scale development, Maximum total mass has different degrees of increase, to increase the used of vehicle driving
Property.At a high speed, frequently braking causes brake efficiency to reduce equally in the safety that threaten road transport commercial vehicle, therefore, automobile
On must install complemental brake system, including engine exhaust and brake, current vortex retarder etc., the system of these complemental brake systems additional
Dynamic effect has apparent improvement, and for heavy vehicle biggish for tonnage, their braking effect is limited.Cause
This, the vehicle equipped with Retarder substantially increases the traffic safety of heavy type commercial automobile, but existing Retarder
Front-cover structure is complicated, and weight is larger, is unfavorable for casting and process, and heat-sinking capability is poor, the position of throttle orifice far from working chamber most
Low dot location be easy to cause oil return unsmooth, influences moment properties and braking ability.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, it is simple to provide a kind of structure, makes working chamber oil return stream
Freely, the Retarder front cover of retarder stopping power is improved.
The utility model solve technical problem the technical solution adopted is that: Retarder front cover includes front cover body, special
Point is that multiple weight loss grooves are circumferentially laid on the end face of front cover body, and working chamber, bearing hole, oil are respectively equipped on front cover body
Sealing of hole, working chamber are connected to oil sealing hole, and oil sealing hole is connected to bearing hole, and working chamber uses arc-shaped inner wall, in corresponding working chamber
The front cover body of the position of minimum point is equipped with throttle valve mounting hole and oil temperature detection device mounting hole, throttle valve mounting hole and oil temperature
Detection device mounting hole is connected to working chamber.
The beneficial effects of the utility model are: Retarder front-cover structure is simple, by circumferentially equal on front cover body
Multiple lightening holes are laid with, by increasing the contact area with air, the heat-sinking capability of working chamber are improved, by corresponding work
The front cover body for making the position of chamber minimum point is equipped with throttle orifice, increases the mobility of working fluid, keeps working chamber oil return smooth,
Effectively improve the braking effect and service life of Retarder.
Detailed description of the invention
It is illustrated below in conjunction with attached drawing with embodiment.
Fig. 1 is the structure chart of Retarder front cover.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the left side view of Fig. 2.
In figure, 1- front cover body；1-1- reinforcing rib；1-2- weight loss groove；1-3- connection boss；1-4- working chamber；1-5- lubrication
Oil groove；1-6- bearing hole；1-7- oil sealing hole；1-8- seal groove；1-9- throttle valve mounting hole；The installation of 1-10- oil temperature detection device
Hole；1-11- dowel hole.
Specific embodiment
Embodiment is respectively equipped with reinforcing rib 1-1, connection boss referring to attached drawing 1-3 on the lid 1 of Retarder front cover
1-3, oil-way 1-5, seal groove 1-8, weight loss groove 1-2, bearing hole 1-6, oil sealing hole 1-7, working chamber 1-4, throttle orifice 1-9,
Dowel hole 1-11, oil temperature detection hole 1-10, weight loss groove 1-2 are circumferentially laid with multiple on lid 1, and working chamber 1-4 is adopted
With arc-shaped inner wall, working chamber 1-4 is connected to oil sealing hole 1-7, and oil sealing hole 1-7 is connected to bearing hole 1-6.In corresponding working chamber 1-
The front cover body 1 of the position of 4 minimum points is equipped with throttle valve mounting hole 1-9 and oil temperature detection device mounting hole 1-10, throttle valve peace
Dress hole 1-9 and oil temperature detection device mounting hole 1-10 is connected to working chamber 1-4.
The working principle of Retarder front cover is: by being circumferentially laid with multiple lightening hole 1-2 on front cover body,
By increasing the contact area with air, the heat-sinking capability of working chamber 1-4 is improved.By in corresponding working chamber 1-4 minimum point
The front cover body 1 of position is equipped with the throttle valve mounting hole 1-9 being connected to working chamber 1-4, keeps working chamber 1-4 reflux unimpeded, effectively
The braking effect and service life of ground raising Retarder.
