Abstract
The invention discloses a gearbox-driven vacuum braking device which comprises a vacuum pump, a gearbox and a transfer box, wherein the transfer box is used for connecting the vacuum pump and the gearbox, the transfer box is installed on the power takeoff opening of the gearbox, the transfer box and the vacuum pump are integrated into a whole, or the transfer box and the vacuum pump are independently installed. On the basis of a traditional vacuum-assisted braking system, one vacuum pump is additionally arranged on the gearbox, a more reliable vacuum degree is supplied by adopting the gearbox-driven vacuum pump, and the device has simple and reasonable structure as well as convenient and flexible installation, avoids the situations that vacuum is adopted as the braking energy source of a vehicle and insufficient vacuum occurs when only one generator-driven vacuum pump exists, greatly increases the vacuum supplying speed of the braking system, guarantees vacuum supply, and improves the safety performance of the whole vehicle.
Description
Technical field
The present invention relates to a kind of vacuum boosting braking system, specifically belong to a kind of gearbox-driven vacuum braking device.
Background technology
Usually, engine petrol can produce higher vacuum pressure at induction maniflod, provides vacuum source but at diesel motor and gasoline direct injection engine vacuum pump need be installed, and satisfies the vacuum boosting braking system requirement.Adopt hydraulic pressure to need force aid system to come driver assistance person to brake as the brake system of transmission medium, the vacuum brake force aid system is to add a cover is provided braking force by other energy work-saving device on the basis of manpower hydraulic braking, make manpower and power dual-purpose, improve braking effect.
At present, the internal-combustion engines vehicle vacuum pump mainly contains two type of drive, and the one, vacuum pump is contained on the engine gear case and is driven by direct geared, and the 2nd, vacuum pump is contained on the electrical generator by generator drive.When needing power steering pump with intergral reservoir is installed simultaneously, power steering pump with intergral reservoir tends to take the installation site of vacuum pump on the gear chamber, so vacuum pump can only be selected to be installed on the electrical generator.When automobile need adopt the vacuum brake source, because structural limitations, the vacuum pump that is contained on the electrical generator often can't satisfy brake system to vacuum requirements, makes the deceleration and stopping performance variation, influences the automobile brake effect thereby especially can cause degree of vacuum to replenish slowly under continuous braking situation.
Summary of the invention
The present invention seeks to: a kind of gearbox-driven vacuum braking device is provided, this apparatus structure advantages of simple, easy for installation flexible, adopt the vacuum brake source and have only under the situation of a generator drive vacuum pump at automobile and remedied the vacuum defect of insufficient well, can avoid great potential safety hazard, improve the safety performance of car load.
Technical scheme of the present invention is: a kind of gearbox-driven vacuum braking device, comprise vacuum pump, change speed gear box, the transfer box that connects vacuum pump and change speed gear box, described transfer box is installed on the power taking mouth of change speed gear box, described transfer box and vacuum pump become one, and perhaps transfer box and vacuum pump are independently installed.
The further technical scheme of the present invention is: a kind of gearbox-driven vacuum braking device, comprise vacuum pump, change speed gear box, the transfer box that connects vacuum pump and change speed gear box, described transfer box is installed on the power taking mouth of change speed gear box, described transfer box and vacuum pump become one, and perhaps transfer box and vacuum pump are independently installed; Described transfer box is connected with the gear mesh of change speed gear box by gear.
The more detailed technical scheme of the present invention is: a kind of gearbox-driven vacuum braking device, comprise vacuum pump, change speed gear box, the transfer box that connects vacuum pump and change speed gear box, described transfer box is installed on the power taking mouth of change speed gear box, described transfer box and vacuum pump become one, and perhaps transfer box and vacuum pump are independently installed; Described transfer box is connected with the gear mesh of change speed gear box by gear; Described vacuum pump and transfer box are installed in change speed gear box left side power taking mouth, and perhaps power taking mouth in right side is perhaps gone up the power taking mouth, perhaps descends the power taking mouth; Described vacuum pump independently is installed in the front of transfer box, perhaps independently is installed in the transfer box back; Described vacuum pump is provided with independently channel for oiling, and perhaps the channel for oiling of vacuum pump communicates with the channel for oiling of driving engine.
Advantage of the present invention is:
The present invention is on traditional vacuum energy assisted braking system basis, on change speed gear box, set up a vacuum pump, adopt change speed gear box to drive vacuum pump failure-free degree of vacuum more is provided, this apparatus structure advantages of simple, easy for installationly flexibly avoid automobile to adopt vacuum to do braking energy source and occurred the situation of vacuum deficiency when only having the vacuum pump of a generator drive, improved brake system vacuum recharge rate greatly, ensure vacuum feed, improved the safety performance of car load.
