Cloth reinforcing rib and inner support strengthening tendons.The lower tank of vacuum tank is obtained using injection molding, is all plastic container, so having
Light weight is easy molding making.Bolt arrangement can be directly mounted at entire vacuum tank on vehicle bracket, brake convenient for vehicle
System assembly.The upper tank body design weldering molded line of vacuum tank, makes upper tank body and lower tank by hot plate welding, is welding as one, has
The high feature of structural strength.
Preferred embodiment is that the inner support strengthening tendons are ring-type, and 6 uniformly distributed reinforcing ribs are divided into interior add by inner support strengthening tendons
Strengthening tendons and external reinforcing ribs, the external reinforcing ribs are trapezoidal shape, and the interior reinforcing rib is triangle, and external reinforcing ribs are set to
On the outer wall of inner support strengthening tendons, interior reinforcing rib is set on the inner wall of inner support strengthening tendons, and the bottom of inner support strengthening tendons is provided with company
Narrow bars, connection strap are connected interior reinforcing rib.Uniformly distributed reinforcing rib is divided into two parts and is connected respectively at inner support strengthening tendons, can be with
So that inner support strengthening tendons and uniformly distributed reinforcing rib are lumped together with better load performance, tank body is not in cracking, and gas leakage is existing
As.The setting of the ring-type, external reinforcing ribs, interior reinforcing rib and connection strap of inner support strengthening tendons, the intracavity space upper tank body are whole
A integrally connected formula reinforces having control note during upper tank body and lower tank carry out injection molding while load performance
Mould the effect of contraction distortion.
Preferred embodiment is that the bolt arrangement includes threaded portion and bolt head, and the bolt head is rectangular
Shape offers grooving on bolt head.Bolt head is done into rectangularity, it is therefore intended that improve torque resistant of the bolt as inserts
Ability；Meanwhile grooving is designed in bolt head, it will be sufficient filling with after plastic injection, and further increase the torque resistant of bolt assembly
Ability.
The beneficial effects of the invention are as follows：Structural strength is high, good seal performance, and cleannes are high, and the service life is long, and light weight is convenient for
The assembly of vehicle braking system.

Sensor, slotting gas nozzle is set on clamping boss fastly；It is provided with side interface on the lateral wall of the upper tank body and lower tank, it is described
Side interface be connected with bolt arrangement
The lower end of the upper tank body and the upper end of lower tank are provided with weldering molded line.
8 uniformly distributed reinforcing ribs 1212 and inner support strengthening tendons 1213 are provided in the inner cavity of upper tank body and lower tank, it is described
Inner support strengthening tendons are ring-type, and 6 uniformly distributed reinforcing ribs are divided into interior reinforcing rib 1217 and external reinforcing ribs 1216, institute by inner support strengthening tendons
The external reinforcing ribs stated are trapezoidal shape, and the interior reinforcing rib is triangle, and external reinforcing ribs are set to the outer wall of inner support strengthening tendons
On, interior reinforcing rib is set on the inner wall of inner support strengthening tendons, and the bottom of inner support strengthening tendons is provided with connection strap 1218, connection strap handle
Interior reinforcing rib is connected.
The bolt arrangement includes threaded portion and bolt head, and the bolt head is rectangle, bolt head
On offer grooving.
The screw thread plug screw is formed by stacking by quadrangle part and circular piece, forms ditch between quadrangle part and circular piece
Slot.
This vacuum tank is divided into two parts composition, and vacuum tank component 1 is welding as one by 11 upper tank body 12 of lower tank hot melt；Welding connects
It is high to close intensity, good seal performance is easy to implement simple, and environmental protection, health are pollution-free, and supplementary product onsumption is not present, at low cost etc. excellent
